Thisinvention is an improvement in web feeding rolls, particularly designed for use in Web printing presses of the-Well-known duplexH type, although applicable to other kinds of presses 'andmachines. is to enable two .webs to be fed tl printing mechanisms at diffe 'that both Webs ma Nol 889,746.

As applied t'o printing presses of the due, for example 5 if the cylinders have a trave suliicient to cover two rows of forms arranged one after the other upon the bed, impressions can be taken on one web from forms thus arranged and impressions can be taken on the other web from a single form placed on the. saine bed..y Thus eight or twelve pages eould be printed simultaneously on oneY web by using a -double row of forms on each. bed, and at` the saine time two pages Could be printed upon the nan-row web by the same beds :nid cylinders lronfi single page. forins placed on the beds. sitnte feeding the -wide web through the press at about'` twiee the speed oll the inn-row web.'

lSpecification of Letters Patent. l Patented .T une 2,' 1908. Application filed August 30, 1907. `Serial No. 390,749.

r reference to the machine illustrated in the accompanying drawfing-in Which- Figure' 1 ,represents diagrammatically a duplex press equipped With my novel feeding and delivering` rolls. 2 is an enlarged sectional View illustrating the con-v struction and mode 'of' gearing the sectional 60 feeding and delivering rolls, whereby two Webs'may be v'fed through the press at diii'erent speeds. Fig; v3 is a detail View of one of the sectional rolls showing one Way in which the roll sectionsmay be locked together. In the drawings l and 2 are type beds adapted to carry two rows of type forms, as' indicated; 13,.. and 2a, are the cylinders, coacting with the forms on said beds. lSaid cylinders may be mounted in sliding carriers 3, reciproeated back and forth by 'means of connecting rods 3 operated by crank wheels 3", asin the duplex press. .The beds and cylinders are preferably arranged .asin the ordinary duplcxpress, and require no deltailed description herein as the construction is well understood. y f

The feeding-in devices 4 and delivery devices 5.are arranged substantially as in the` duplex press, .and the guides and looping vdevices for handling theniain web are arranged substantially as in the duplex press and need no detailed description: but will be readily understood by following the course oi' what I shall terni herein the Wide So web indie-ated :it in the drawings. 'llus 4web"-'\V is led in under n luide' and between the l'eed rolls 4 down under the guide ti, up over looping roller 6h, down under a guide o, to and over guide (Se, then between bed. l and cylinder l, up ov-"L' guide 6i, bueh to. under nnd over guides ti, (il, back oy'er guide .tibetween eylinder 2" and bed 2; lhenee over guide o to guide (if, then down under loopingl roller t'i, then up orer guide 95 t3" toy the delivery rolls` ."f 'lhe guides 6", l", (ih-ti, :1re mounted on the Cylinder Oni'- riersI nlnl travel ith ,the cylinder. The loopingl rollers o" nud ti :tre int-nnited-in :1-

reciprocating traine N, which is operated by 10Q Y means-ot' nlinh N eonneeted to a lever 8". which is ribrnted by means ol cam S". as in the duplex press: the parts being opt-r- :ited in sueh lnnnner that during the taking ol' an impression, while the cylinders 1, 2"', 105

nre rolling over the Lyne, toi-ins, the web fed 4flin by the feeding rollers is taken 11p-bythe 'tween the beds andcylinders to bring unprinted portions of the 'web into position to be printed vat the next movement of the cylinders over the forms. The web w, which I will call the slow web, is guided similarly through the press but is operated at sayhalf thesp'eed of web W. In order to feed and deliver this web w at half speed I make the feed and delivery rolls 4 and 5 in sections, as indicated in Figs. 2 and 3; the fast section 4a of roll 4 is fixed to the shaft 4b which isdriven, by a suitable train of Vgears 4" from the drive shaft, at `the proper speed to feed the. web W' into the press with the desired rapidity.

The slow section 4 of the feed roll 4 is preferably rotatably mounted on shaft 4b and is driven, at say half the speed of section 4', by means ol the. pinion 4f fast on section 4 meshing with a plnon 4g on a stub shaft 4h journaled in the frame and carry ing a gear 4" meshing with a gear 4j keyed on the shaft 4", so that the slow section 4e is driven from shaft 4b at a speed different from that of section 4, The ydelivery roll 5vis similarly constructed with fast and slow sections 5, 5, which are driven, at the same speed as the sections 4, 4e, ofthe in-feed roll, by means of trains'of gears 4d and 4, as indicated in Fig. 2 of the drawing.

By properly proportioning lor varying the diameters of gears 45, 4i, any desired ,difference between the peripheral speeds of sections 4?, 4e, can be obtained; and where a full width web is to be printed, the sections may be driven at the same speed by substituting gears 4i, 45. Or by removing gear 4g and ocking sections 4e, 5e, res ectively to the sections 4, 5a, or their sha ts. i

The arrangement of forms' for printing A any even numberof pages on one web wil be obvious to pressmen and need not be described herein. When a full Width web is to be printed to roduce say 16 pages, thevgears 4i, 4j, can fie changed so that the slow sections 4", 5e, will be driven at the same s eed as the sections 4*?, 5, and then the wi e web is led through the press like web W above described, and the loopingrollers 7a, 7m, not be used.

VIf it be desired `to handle a Wide web through the press at slow speed, it will only bel necessary to alter'the gearing so astodrive both sections at the slow speed. Or ifl suitably proportioned gears for they seams desired in order to drive sections 4a, 5, at slow speed,.like sectionsii`e 5e, the section 4, can be unlocked from its shaft 4b by withdrawing the key 4x, and locked to section 4e in any desired manner, as for instance by a screw 45' engaging a shoulder 4 on section 4e, as indicated in Fig. 3. Section roll 5 could be similarly constructed. This beingmerely a matter of mechanical selection and construction I do not wish to be restricted to any particular construction whereby the two lsections of rolls 4 and 5 may be driven alike', at either fast or slow speed. When the sec- L' tions are driven alike' at slow speed, a Wide web canA be led vthrough the press like web w and'looping rollers 6b, 6m, will not be used.

VThus I can run through this press a single wide `web at slow or fast speed; or two nar-v row webs at different speeds.

Assuming that .two webs are to and that the slow sections 4", 5e, are geared at half the s eed of 'the fast sections 4, 53,1 the'narrow web w one-,half as so as to fee fast as the wide web W, it isnecessary to provide means for looping the web w in accordance ,with its slower in-feed and delivery. A very simple and effective ,way of'looping this web is indicatedI in the drawings. As shown, web w passes from a roll under guide 2X to and over the slow infeed section 4e, and thence under a fixed guide '7n over a loop ing roller 7b, down under, guide, .7 C, and thence over the gufide 6e beside and along with the wide web W. to and between the beds and cylinders and on as far as guide 6k;

4then the narrow web w passes over a guide 7l, down under a looping roller 7", up over a uide 7n to the slow feed section 5e .of the deivery mechanism. The looping rollers 7'? and 7m are mounted in a frame 9, which is pivotally connected at 9@ to a lever 9, which is pivotedat 9b to a fixed point of the frame and its forward free end is pivoted at 9c to the frame 8, as shown. The pivot 9d is' midway between the pivots 9b and 9C and there, fore the frame 9 will be moved by and with the frame 8 but will only move half the distance traveled by frame 8, consequently the looping rollers 7 b, 7m, will only move half the distance of the looping rollers 626m, and at half the speed of the latter, and thus the -web w will be looped exactly in accordance claim as new and desire to secure by Letters Patent is:

1. In a webprinting press, the combination of a roll having two sections, one of said sections being fast to the roll` shaft and the be printed, I

speeds and gearing between the res eet-ive other loose thereon', means for driying said l seotlonsof the feed roll and the simi ar secshaft,` a gear on said shaft beside the loose section, and changeable gearing between tions ofthe delivery roll. suoli gear and the loose .section whereby the l In testimony that I claim the foregoing as 15 latter is driven from the shaft of the roll at a, my own, l aiii'x my signature in presence of different Speed.- l i two Witnesses.

2. ln a web printing ress, the' combination of a Web feeding ro l, and a- Web delivery roll eaeh having a 4plurality of sections, means whereby the sections of the feed roll may be driven at the same or at dii-ferent v HENRY F. BECHMAN.
